Thirteen minutes into his debut at Ajax in March 2020, Jurrien Timber lived a nightmare.
Ajax's 18-year-old prodigy watched as Hicham Faik's free-kick zipped around a two-man wall and thudded into Andre Onana's net. Heerenveen 1, Ajax 0.
It was a free-kick he had needlessly given away and been booked for, and one which left Erik ten Hag's team on shaky ground as they tried to chase down AZ Alkmaar at the top of Eredivisie.
In other words, not a great start. And it turned out there was little time to make amends - after Ajax won 3-1 to move into top spot, Covid-19 ended the season.
